A system is defined to be a collection of related things. Therefore, all systems can be defined as a tuple of set of things, and a set of relations.

A system  $S$  can be defined as a tuple:  $\{T,R\}$ ,

where

 $T$  is a collection of things,  $T=\{t|t\in T\}$  and 
 $R$  is a set of relations that relates two things  $t\in T$ .
